Answer:
D. 59.50$
Step-by-step explanation:
Lets make an equation:
we know she is going to use 2 parts of yellow to 3 parts of red and she needs 10 quarts, therefore the equation would be:
2x+3x=10
x = 2
2 * 2 = 4( we need four quarts of yellow paint)
Price for yellow paint = 4 * 5.50 = 22
2 * 3 = 6(we need 6 quarts of red paint)
Price for red paint = 6 * 6.25 37.5
Add those prices: 37.5 + 22 = 59.50$
Ignore the height (3) and concentrate on the length and width of the bottom:
The bottom is 15 cm by 3 cm, and so the diagonal of the bottom is
sqrt(15^2 + 3^2) = sqrt(225+9) = sqrt(334).
